How big is your tank? What decorations do you have?
And they are very good with other fish (as long as the fish aren't aggressive or want to eat them). I would recommend smaller fish. They can be housed with neon tetras, they usually aren't aggressive. I had mine for a little over 4 years. Male and Female. I named them jack and jill, but I didn't know their genders until a few weeks ago (I made journals about them and drew pictures of them)
Anywho, I have loved them! They are really fun and are cool to watch. Every frog is different and have their likes and dislikes. They do shed their skin though. Sometimes they will eat it, sometimes they don't Often times the fish will eat it and I haven't ever had mine get sick from it. You can choose to take it out or keep it in (skins).
